Case 6-6. Non-Proliferative Diabetic Retinopathy and Cystoid Macular Edema
A 71-vear-old woman with a three vear history of
adult-onset diabetes mellitus was referred for mild nonproliferative diabetic retinopathy and clinically significant macular edema in her left eye. The visual acuity in this eye was 20/70 (A). Fluorescein angiography (B) displayed late leakage in the fovea consistent with cystoid macular edema.
A series of vertical OCT tomograms (C) was obtained through the macula providing three-dimensional information on retinal structure. The retinal thickness was increased in the macula/ with large areas of low reflectivity corresponding to intra retinal cysts and fluid accumulation. The retinal thickness measured in scan D, taken directly through the patient's point of fixation, was 650 Jim.
